My Whisperflo 1 HP motor finally died after 15 years. The replacement VS pump will not be installed for another week. The summer sun is unforgiving out here in Northern California. Not to mention it has been hot. I’m doing all I can to prevent algae. I can’t leave it unfiltered for another week. Since I hardly use my sheer descent pump, I’m thinking of temporarily swapping the motors. They are both Whisperflo. The difference is the sheer descent motor is 2 HP. Can I swap them temporarily? I have a feeling the answer is no but thought I should ask anyway.

Success! I swapped the motors and we’re back in business.

It's ok to go up in HP but not down. The reason for that is the impeller size. Using a 1Hp impeller on a 2HP motor is ok. However, a 3/4HP motor would burn up quickly trying to spin a 1HP impeller.
